Technically the bullets are .224 cal, they are assumed to be fired from a .223 cal rifle (most common). The media is jumping to conclusions and hoping it is an assult weapon. Even though it could be anything from a .222 to a .22-250.

I want to see the interview(if/when it happens) with the so-called witness who is purported to have seen the guy "step out of vehicle, shoot, and get back in"....

ABC reported last night a possible connection to the Baltimore guy...per FOX......

Police are saying they think the sniper responded last night to this ABC report...they are "concerned and upset"..

No problem, I always enjoy firearms trivia. For instance, the .223Rem began its life as the .222 Special, which was developed by none other than Eugene Stoner. There were already a few other .222 rounds in existance (like the .222Win), so the round was retitled the .223Rem in order to avoid confusion.

Also, to expound on the difference between the 5.56 and the .223, since the 5.56 has a longer neck, it could jam in a .223 barrel. There's also more powder, so, when fired, that puts the pressure out of SAAMI specs. Therefore, it's safe to shoot both 5.56 and .223 out of a 5.56 barrel (which specs most are made to, anyway), but NOT 5.56 out of a .223 barrel.

Even though it could be anything from a .222 to a .22-250.

Posters keep saying this, but I believe, unless it's reloads or homemade bullets, that the weapon, or at least the barrel. can be identified. There have to be differences between manufacturers and models that can be seen in the recovered slug. I bet there are significant differences in the weight and composition of various commercial cartriges. Can anybody prove me wrong?

Don't forget the .220 Swift.
